PROCESS OF MAKING NOZZLES.

Applicatinn filed November 28, 1924. Serial No. 752,526.

My invention relates to nozzles such as are commonly used in connection with steam boilers and the like, and contemplates a new and improved process of making them.

in. the accompanying drawing the successive ligu res illustrate the successive steps in the process of my invention, although it will appear that the precise order 01' the steps, in the broader aspects of my invention, may be varied, and the appended claims have been drawn accordingly. The figures are all cross sectional. views, with the exception ol Figure 3, which is a plan view of the ingot in the fOl'lIiE-illO'Wll in .l igure 2.

'lthe billetoil wrought metal, from which the nozzle is to be formed is shown at u. ly the first step in the process this billet heated and iiiorined, by means oi? dies,

into a circular body '7) having a flange c, at the bottom thereo'l, as shown in Figures 2 and 3, and a central depression (Z is formed in the top thcreolf. This depression (Z is termed as part of the step of providing a through central opening as will be clear presently.

The next step in the process is to coinplcte or town the through central opening (2, as shown. in Figure l, this being accomplished by rei'noving the inetalbelow the depression (Z and sulticiently more to eflect a uniform diameter.

Tllhc next step in the process is to form the peripheral v oove y, whereby an integral structure comprising an upper flange, a lowor flange and a coi'inecting neck is formed, as shown in Figure 5. This groove is preferably flO'lnlQtl by inserting a mandrel in the openii'ig c and applying rolling dies moving toward the axis as indicated by the arrows, the billet being properly confined between upper and lower dies to insure the form oi the flanges and the proper nozzle length. The groove f may also be formed by cutting in a lathe, in which event. the nozzle length is determined in the first instance, i. e., in the ilorn'iation illustrated in Figure Q.

The last step in the process is to bend the lower flange into cylindrical form, as shown in Figure 6, so that it may fit properly the boiler or the like to which it is to be secured.

I claim:

1. The process of forming nozzles which comprises first forming a circular body with a. flange at one end and with a central opening of substantially ultimate size there through, and then :lorining a peripheral groove in said body adjacent said flange to form a central neck and a flange on the other end of said neck.

2. The process 01' liorn'iing nozzles which comprises. ii'orn'iing a circular body with a flange at one end and with a central opening of substantially ultimate size there through, and rolling a peripheral groove in said body adjzurentsaid flange to ifOllll a central neck and a flange on the other end of said neck.

3. The process of forming nozzles which comprises jliorn'iing a circular body with a flange at one end and with a central opening of substantially ultimate size therethrough, forming a peripheral groove in said body adjacent said flange to Tl'Ol'lll a central neck and a flange on the other end of said neck, and bending one of said flanges into cylindrical lOIlI].

4.. The process of forming nozzles which comprises first forming a circular body with a flange at one end and with a central depression in the other end, then removing the metal in line with said depression to form a through central opening of substantially ultimate size, and then forming a peripheral groove in said body adjacent said flange to form a central. neck and a flange on the other end oi? said. neck.

5. The process oil? torn'iing nozzles which comprises "forming a circular body with a flange at one end and with a central opening o'l substantially ultimate size thcrethrough, rolling a taller-shaped peripheral groove in said body adjacent said flange to form a central. neck and a flange on the other end of said neclr, and bending one oi said flanges into cylindrical form.

In witness whereof, I hereunto subscribe my name this 18th day of November, 1924:.

JAMES HALL TAYLOR.
